Black Throat Monitor

Black Throat Monitors (Varanus albigularis ionidesi) are a large, powerful monitor lizard native to East Africa. They are one of the largest monitor species kept in captivity, with adults regularly reaching 4–6 feet in length and weighing 20–50+ lbs. Despite their size, Black Throats are known for being one of the more docile and intelligent monitor species — many become quite tame with consistent, patient handling. They are a long-term commitment of 15–25 years and require very large, custom-built enclosures. Strictly for experienced reptile keepers.

Black Throat Monitors are highly intelligent and can recognize their owners. Juveniles may be defensive and whip with their tail — patience and consistent calm handling is key. Well-socialized adults become very tame and can be quite interactive. They are inquisitive and will investigate everything in their environment.

Maintain temperature gradient and UVB. Refresh water in soaking dish. Spot-clean substrate. Feed on schedule. Monitor for shedding and assist if needed. Handle regularly to maintain tameness.

Black Throat Monitors are carnivores and should be fed a varied diet of whole prey: • Juveniles: appropriately sized insects (dubia roaches, superworms), pinky/fuzzy mice, hard-boiled eggs • Sub-adults/Adults: rats, rabbits, whole fish, quail, eggs, snails Dust insects with calcium + D3 for juveniles. Whole prey items provide adequate nutrition for adults. Feed juveniles every 1–2 days; adults 1–2 times per week. ❌ AVOID: processed meats, dog/cat food as a staple, high-fat foods long-term.

Adults require an enclosure of at least 8x4x4 ft — custom builds are nearly always necessary. Provide a deep substrate (12+ inches) of a soil/sand mix for burrowing. Include a large water basin for soaking, sturdy basking structures, and multiple hides. The enclosure must be extremely secure — Black Throats are powerful and will test every seam.

Basking spot: 120°F–140°F (surface temp). Ambient warm side: 85°F–90°F. Cool side: 75°F–80°F. Nighttime drop to 70°F–75°F is fine. UVB lighting (T5 HO 10.0 or equivalent) is essential. Replace every 6 months. Humidity: 50%–70%. Provide a large soaking dish and mist one side of the enclosure to create a humidity gradient.
